How does the aluminum work for you? We used this steel thinking that, with all the holes being drilled, it needed all the strength it could get. BTW, with this hole, I have room for my glowire, but not 2 runs - so it'll take a separate wire for each stick.
It's strong enough. My really scientific stress test entailed just cutting the shaft to length, then trying to bend it with my bare hands.

They passed the test, and should at least hold up until I have kids...
I had a really complex idea for a framework inside the base, but I'll probably just thicken the shaft enough to keep it from spinning easily. Although after looking at your cool method, I may just give that a whirl! (but dude, you need a better digital camera!
)
I had originally planned to have 4 nails coming out of the shaft and 4 slots in the base, but realized that 1 would work just as well. It was the simplest idea I could come up with that wouldn't hamper movement of the sticks. You just need to make sure the nail is as far down on the spacer as possible, or it can pop out of the slot when the stick is pulled all the way back.
And, yeah, my camera sucks, but hey, it was free!

Maybe Santa (or Ms. 1UP) will leave something with 2 or 3 megapixels under the tree this year...

Actually, in your hack, it would also prevent someone from spinning the stick around several times and twisting up and possibly cutting the wires under the CP. Hmmm... fragile things there are.
Yup, that's pretty much the idea.
